摘要

Wheel chain (1) has a safety, which is arranged at the tension chain (6) and the two non-adjacent chain members of the tension chain are interconnected, and in forming a reserve length, shortens the tension chain. The safety is opened with a definite tensile load, which is smaller than the breaking load of the tension chain and wheel lattice members.
